Polymeric rheology modifiers

摘要

The present invention relates to acrylate-based, associative polymeric rheology modifier prepared by polymerization of a C1-C6 alkyl ester of acrylic acid and/or a C1-C6 alkyl ester of methacrylic acid, a monomer chosen from a vinyl-substituted heterocyclic compound containing at least one of a nitrogen or sulfur atom, (meth)acrylamide, a mono- or di- (C1-C4)alkylamino (C1-C4)alkyl (meth)acrylate, a mono or di-(C1-C4)alkylamino (C1-C4)alkyl (meth)acrylamide, and an associative monomer.
